vTo all 'whom it may concern Be it known that'fI,WViLLrAi\i` W. WILSON,

a citizen of the United States, and a residenty ofDorchester, county of Suffolk, *State of Massachusetts, (whose post-oliiceaddress is 23 Benthamroad, Dorchester, Massachu- "fsettsj have inventedganA Improvement `in Column-Molds, of lwhich the following description, in connection with the accompanying drawings, is a specification, likeletters on the drawings-representing like parts.

This inventionrelates to monolithic 'column molds being'more particularly intended to'provide a superior form ofmoldwhich' can also be erected and dismantlcdat slight*` expense. u' My invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in theappended claims. InA thek drawings; lI `igure"`1 is an elevation partly broken away showingajcolumn mold embodying one form of the invention;4

Fig. Q- is a. sectiontin plan ,on theline 2;-2 in Fig. l; but on a larger scale; and Fig.' 3

is a similar section on the line in Fig.- 1f Referring to the drawingsand to' theem-l bodiment'of the invention there shown,I have illustrated one form of ,a column mold for molding a concrete or other similar monolithic column l; `In preparingamold for a column of this kind, it is customary tol form the sides ofthe mold 'ofl'ongitudinally arranged matched molding boardsv or'other' suitable molding members 2. These are held in place by means of a number of cross bars or cleats which are arranged transversely at intervals to overlie the molding boards, these cross bars being customarily arranged in sets of four, opposite pairsv of which are held in place by bolts, this serving to clamp or bind the sides of the mold together and give rigidity to the structure.

It is necessary tol use the cross bars at frequent intervals, and, each pair of bars having a pair of bolts, the labor of constructing the mold and particularly of erecting it forms a heavy item of expense in this type of construction. It is also difficult to make it of uniform rigidity and dimensions throughout its length.

Through the use of my invention I eliminate the necessity of bolts for each pair of coLniyiiLMoLn. A g; ,f y f cross bars; This is secured .by utilizing longitudinal stripswhich'overlie ends ofthe speclilfionoflttersafeni. Patented sepas, 1914; f. Appiiceaenfneancember'ie,1910. seriaineseaem,

cross-:bars so that' whenopposite strips are looltedftogether attwo or three points all intervening cross bai-sare clamped in tightly against the'sides "ofthe mold. `This greatly 'reduces the labor-required 1in erecting and dismantling the mold and provides a more' rigid vmold, uniformv throughout Aits length.

,It also permits theusel lof cross bars of smallerl dimensionsfsince the strain .in the*k mold iS lessened.`

V It lferringto thedrawings, I haveshown the molding boards 2 provided on opposite sidesfoffthe mold withj'aseries of cleats or crosslo'ars 3, herein `of wood, although metal maybe used ifldesired, the Vcross'liars being arrangedfin double pairs, one pair foreach two opposite -sides of the mold and used in sufiicientnun'ibers .to give the required ri" .gidityfto'they structure. n Q Herein-.seven such sets of'crossbars, are

utilized,` each bar being nailed or otherwise attached lto` thesides ofthe molding ,boards The opposite members ofeach pair'are drawn together to clamp the molding boards l betweenvthem, by longitudinal strips, preferably', though not necessarily, vin the'form *t of angle ironst'which extend'lengthwise the t" column4 and overliejthe ends ,of the cross bars, the latter l'preferably yproj ecting` somewhatfbeyond the limits of fthe molding boards. `r"The angle irons or other stripsbe-y ingl placed over these projectingends, the

bolts 5 aretheneinployed-to clamptheiirons together at any rappropriate points', pref* erably,"however, near the top and bottom' of the mold and at one or more intermediate points according to the dimensions of the mold. Herein the angle irons are bolted together at the top and bottom of the rcolumn and near the mid portion thereof, each angle iron being joined lto the ynext adjacent one by three separate bolts which lie outside of themoldboards 2. While the bolts might also pass through the projecting ends of the cross bars, preferably they are arranged intermediate the latter so thatno one of the cross bars' requires a hole to be bored in it. The strips or angle irons may be drilled at frequent intervals as represented so that the bolts maybe inserted at any point required.

Theedescribed form of column mold can be erected and dismantled in less than half the time than the molds heretofore used and lVhile I have liereinshown and described for purposes of illustration, one specific form of the invention, it is to be understood that extensive deviations may be made tlierefrom yWithout departing from the spirit thereof.
